Chazmire purchases 14 bags of flour for her bakery.Each bag of flour cost $2.47. How much does chazmire soend for flout
Answers
Answer:
$34.58
Step-by-step explanation:
If each bag of flour cost $2.47, then;
1 bag = $2.47
To calculate the cost of 14bags;
14 bags = x
x is the cost of 14 bags
Divide both expressions
1/14 = 2.47/x
cross multiply
1 * x = 14 * 2.47
x = $34.58
Hence Chazmire spent $34.58 on flour

Answers
Answer:
the answer is (5426)
Step-by-step explanation:
i got the answer online
The space inside the cone is 5426 cubic feet
What is the volume of a cone?
The formula for the volume of a cone is V = ( 1 / 3 ) πr²h.
Given data ,
Diameter of cone = 24 ft
Radius of cone = ( Diameter of cone / 2 ) = 12 ft
Height of cone = 36 ft
Space inside the cone = Volume of cone
Volume of Cone = ( 1 / 3 ) πr²h
= ( 1 / 3 ) x ( 22 / 7 ) x 12 x 12 x 36
= ( 22 / 7 ) x 48 x 36
= ( 22 / 7 ) x 1728
≈ 5426 cubic feet
Hence , the space inside the cone is 5426 cubic feet

*5. Gina's sister is 9 years older than Gina. Their combined ages add up to
49. How old is Gina? *
A. 29 years
B. 20 years
C. 19 years
D. 9 years
Answers
Answer:
B. 20 years
Step-by-step explanation:
By using the process of trial and error, if Gina is 20 years old, that would mean her sister is 29 years old. This is because 20+9 is equal to 29. 29+20 sums up to 49.
Answer: B. 20 years
Step-by-step explanation:
we will represent Gina sister's age by x and Gina's age by y.
Now were know that the age of Gina sister is 9 years older than Gina's so we can represent that by the equation x = y + 9
If we add their ages it is 49 so we can also represent that by the equation,
x + y = 49.
x = y + 9
x + y = 49
Using both equations, substitute x in the first equation into the second equation and solve for y.
(y + 9) + y = 49 solve for y , by first combining like terms.
2y + 9 = 49 subtract 9 from both sides
-9 -9
2y = 40 divide both sides by 2
y = 20
Since y was used to represent the age of Gina then Gina will be 20 years old.

Answer:
44.2545
Step-by-step explanation:
you can find the third angle by taking 180-(90+55)=a
a=35
use law of sines
Sin(angle)/(opposite side of angle)=Sin(another angle)/(opposite side of another angle)
so, sin(a)/A=sin(b)/B
sin(35)/33=sin(55)/x
x=sin(55)/(sin(35)/33)
x=44.2545

if a - b = 4 and a² - b² =12, what is the value of a + b?.
help.
Answers
Answer:
a² - b² = ± 32
Step-by-step explanation:
⇒ a + b = 4
⇒ a = 4 - b ... ( 1 )
Substituting this in another equation we get,
⇒ ab = -12
⇒ ( 4 - b ) ( b ) = -12
⇒ 4b - b² = -12
⇒ b² - 4b - 12 = 0
⇒ b² - 6b + 2b - 12 = 0
⇒ b ( b - 6 ) + 2 ( b - 6 ) = 0
⇒ ( b + 2 ) ( b - 6 ) = 0
⇒ b = -2, 6
Case 1: If b = -2
⇒ a = 4 - b
⇒ 4 - ( -2 ) = 4 + 2 = 6
Case 2: If b = 6
⇒ a = 4 - b = 4 - 6 = -2
Hence the numbers are 6 and -2.
⇒ a² - b² = ?
Case 1: a = 6 and b = -2
⇒ ( 6 )² - ( -2 )²
⇒ 36 - 4 = 32
Case 2: a = -2, b = 6
⇒ ( -2 )² - ( 6 )²
⇒ 4 - 36 = -32
Hence the answer for a² - b² can be ± 32 depending on the values of a and b.

If Debbie starts a retirement account with 10,000 dollars that has an annual rate of return of 12%, how long (in years) would it take for her to have at least 100,000 dollars if interest is compounded continuously?
Answers
Answer:
19.2 years
Step-by-step explanation:
The formula to find the time in a compound interest that is compounded continuously is given as:
t = ln(A/P) / r
Where:
t = time in years = ??
A = Amount after Interest is compounded continuously = $100,000
P = Initial Amount in the retirement account = $10,000
r = Rate of return = 12%
First, convert R percent to r a decimal
r = R/100
r = 12%/100
r = 0.12 per year,
Then, solve our equation for t
t = ln(A/P) / r
t = ln(100,000.00/10,000.00) / 0.12
t = 19.188 years
Approximately t = 19.2 years
